My son had knee surgery on his right knee about two weeks later he developed a blood clot in the same leg. They put him on Cumadin 5 mg a day. A week later he had his levels checked and they were 9.3. My question is shouldn't he have been hospitalized for this high of count and if not what is the typical protocol for levels this high. All they did was stop the cumadin and are running a CT. Outpatient only. Thank you memabe15
